Chicken Rock (Manx: Carrick ny Kirkey), part of Rushen parish, is the southernmost island administered by the Isle of Man. It lies southwest of the Calf of Man, 4.5 kilometres (2.8 mi) off Spanish Head on the Manx mainland. The most prominent feature of the rock is the 19th century Chicken Rock Lighthouse. The 44 metres (144 ft) lighthouse was first lit in 1875, and is owned and maintained by the Northern Lighthouse Board.
